The reason is that they're hollow, unlike permanent ones which are cement-filled. 

We have done almost all of the work ourselves thus far including:New kitchen and opening of floor plan on first floor (not completed- still needs trim and some custom cabinetry)New deck and sliding doorsRework of 2nd floor to add bigger closets, 2nd floor laundry and new larger bathroom (bathroom not completed)Total cost of renovations so far: $25kThe reason we only paid $154 is because the stairs to the 3rd floor are in the 2nd floor bathroom!

The home will be completed in a total time of ~6 weeks, with completely new kitchen and baths, new drywall, new roof, exterior repairs to the cement, new hot water heater and new HVAC.

This year I added a 4 plex with a restaurant down stairs and 2 single families. 

They only thing he wanted was to add a railing on the front porch stairs.

It has 4 shops and an efficiency apartment on the first floor, and unfinished space upstairs with inside stair access, a cargo elevator and potential to build exterior stair access.

New tenant just moved in about 2 weeks ago and stated today that there is a strong marijuana smell in her storage space, (under her stairs) that is making her whole unit smell and she believes it is coming from the neighbors next door.   

Thanks.Looking for 1700 sqft(including stairs and extra for storage, future replacements of individual planks)Budget < or = $4 per sqft before Discounts if thru Lowe/Homedepot, mind us - Seattle is 10.1% taxThank you everyone

I won't describe here all of the things things he saw on the tape but it did involve drug use and people relieving themselves in the stair wells, as well as a romantic relationship with an employee and tenant.I will try to summarize the positive experiences of my months as a leasing agent.I did learn a lot about property management software,entering payments on time, and keeping up moral in the community by hosting monthly parties.
